FIELD: power engineering, more particularly preparation of cheap and economical sources of energy. SUBSTANCE: overheated steam having temperature of 500-550 C is produced in unclosed space. Overheated steam is passed through constant high-intensity electrical field (6000 V) to produce hydrogen and oxygen. Method sues simple equipment, is economical, fire-and explosion safe, and is highly efficient. EFFECT: more efficient preparation method. 3 dwg
